The terminal block, TB1, allows the user to apply an alternate power source to the board. In-
put voltage, +VIN, should remain between +7VDC and +18VDC. TB1 accepts wire sizes
ranging from 28AWG to 16AWG.
Terminal block position 1 connects directly to the EVB VDD rail. This may be used to drive the
voltage rail directly or may be used to provide power to external circuitry. Caution must be ex-
ercised when using this input since no protection is provided.

PWRSW Power Switch
The PWRSW easily connects and disconnects input voltage to the board. The silkscreen
clearly marks the ON and OFF positions. This switch controls all voltage levels on the board.
Voltage Indicators
The +3.3V and +5V LED indicates availability of the associated voltage rail.
VDD_SEL Option Header
VDD_SEL allows the user to selectively apply +5V or +3.3V to the VDD rail on the EVB. Re-
gardless of the voltage level selected, +5V is available to the USB VBUS output for USB HOST
mode applications.
PWR_SEL Option Header
The PWR_SEL option header selects the source of input power to the EVB. The board may
be powered from a voltage source connected to either the PWR connector or the terminal
block. The board may also be powered from the integrated USB BDM. The BDM can provide
up to 350mA of current to the EVB.
